当前提高农民工的务工收入是解决农民工诸问题的关键,社会资本对农民工收入有很大影响。从社会资本角度考虑增加农民工收入的方法主要是增加信息流通。从调查中发现信息流通与农民工收入的关系十分紧密。工会传统的组织形式和原有职能不能在农民工问题上起到有效作用,工会应该转变职能,承担起信息流通的任务,有助于找到解决问题的途径。 At present, raising migrant workers 'work income is the key to solving the problems of migrant workers, and social capital has a great impact on migrant workers' income. From the perspective of social capital to increase income of migrant workers is mainly to increase the flow of information. From the survey found that the flow of information and migrant workers income is very close. The traditional organizational form of the trade union and the original functions can not play an effective role in the issue of migrant workers. The trade unions should change their functions and assume the task of information circulation, helping to find a solution to the problem.
